DroidSat

DroidSat is an innovative application that transforms your mobile device into a real-time satellite tracker. Aimed predominantly at advanced users with a penchant for astronomy and satellite tracking, this app allows you to point your handset skywards and identify which satellites are overhead at any given moment. The software is designed to operate offline, after the initial satellite files have been downloaded, meaning no network connection is needed for real-time tracking — a true advantage for users in remote locations or where connectivity is limited.

One of the key features is the ability to load custom satellite TLE (Two-Line Element set) files, enabling enthusiasts to track specific satellites of personal or professional interest. Additionally, it offers highly configurable display settings, optimizing your device's CPU usage while saving power — a thoughtful touch that extends your tracking sessions.

With this satellite tracking tool, you can not only observe current satellite positions but also utilize the fast-forward function to forecast and visualize their future orbital paths. Before launching the game, users should ensure their GPS location is enabled and that they have an active internet connection for the initial setup.

The software offers an intuitive menu system, allowing you to choose different categories of satellites such as the ISS, the brightest ones, or recent launches. Users can adjust the playback speed to accelerate the display of satellite movement, and the program also provides the capability to regularly update the TLEs, ensuring that the satellite database remains current.

The game stands out for its robust customization options. In the preferences section, you can fine-tune display properties, including color settings, to personalize your viewing experience. For those who wish to utilize their own TLE files, it makes it simple to transfer them to the designated storage path on your device.

Comprehensive instructions are readily available, ensuring a smooth user experience. The core functionality relies on Horst Meyerdierks' Sputnik 3.1 Java program for precise satellite position calculations, tapping into regularly updated orbital data sources. Engage with the marvels of space and track the celestial dance of satellites at your fingertips with DroidSat.
